We're dividing 849639 by 63 
Let's see how many times 63 fits into 849639.

Moving on to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 63

Moving on to step 2:
If we divide 84 by 63, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 63 from 84 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 63

Advancing to step 3:
63 goes into 219 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 189 from 219 and we're left with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 63

Moving on to step 4:
63 can be fit into 306 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 252 from 306 leaves us with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 63

Advancing to step 5:
63 goes into 543 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 1348.0
Deduct 504 from 543 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 63

On to step 6:
63 can be fit into 399 6 times, resulting in a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 13486.0
Subtracting 378 from 399 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
63 goes into 210 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 13486.3
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
63 goes into 210 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 13486.33
The remainder is 21 after subtracting 189 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 13486.33 with a balance of 0.021.
